If you could just help me out I would be great! Im not asking for answers fully but if you could just give me a link to some help it would make my day. Thanks so much.
What da answers bro..I finna get the belt
1. Use unit rate
2. 12 X 15
3. 3 X 75
hope this helps
whats the answer
Sure! I'd be happy to help you out. Let's go through each question and explain how to get the answer:
1. For the first question, we are looking for the statement that demonstrates unit rate. A unit rate is a rate where one quantity changes with respect to one unit of another quantity. In this case, we need to find the statement where one quantity changes in relation to one unit of another quantity.
- Statement A doesn't provide any information about rates or ratios.
- Statement B tells us that Rita drives at 50 miles per hour, which is a rate since it relates the distance (miles) to the time (hours). This is an example of a unit rate.
- Statement C doesn't provide any specific rate or ratio.
- Statement D tells us that the school has 90 children for every 3 buses, which can be simplified to a rate of 30 children per bus. This is also an example of a unit rate.
Therefore, the correct answer is B. Rita drives a car at 50 miles per hour.
2. For the second question, we need to use the information from Kara's table to calculate how many apples she needs to make 12 pies.
- From the table, we can see that Kara needs 15 apples to make 2 pies. This gives us a rate of 15 apples per 2 pies, which can be simplified to 7.5 apples per pie.
- To find how many apples Kara needs to make 12 pies, we can multiply the rate by 12: 7.5 x 12 = 90 apples.
Therefore, the correct answer is C. Kara will need 90 apples to make 12 pies.
3. For the third question, we are given that Cheryl went on a 3-hour train ride at an average speed of 75 miles per hour. To find the total distance Cheryl traveled, we can multiply the speed by the time: 75 miles/hour x 3 hours = 225 miles.
Therefore, the correct answer is A. Cheryl traveled a total distance of 225 miles.
